Dye intermediates generally refer to different kind of aromatic derivatives which are always used in the production of dyes or in dyes and dye intermediates industry.
Dye intermediates, including Benzene series intermediates, Toluene series intermediates, and Anthraquinone series intermediates. In addition, there are some Heterocyclic intermediates. The reaction of dye intermediates manufacturing process commonly used in the production of pigment intermediates mainly include Nitration, Sulfonation, Halogenation, Reduction, Amination, Hydrolysis, Oxidation, Condensation, etc. The synthesis of dyestuff intermediates with a more complex structure often requires many unit reaction intermediate chemistry, and sometimes different basic raw materials and different synthetic routes can be used. We keep finding the dye intermediates meaning in order to generate more products as well as intermediate pharmaceutical products with good quality.
For example, in the production of 4-Nitroaniline is initially nitrated and reduced to obtain Aniline, followed by acetylation and hydrolysis and others.
As one of the professional dye intermediates manufacturers as well as a china active pharmaceutical ingredient company, we not only supply the dye intermediates but also have the complete technology book on dyes & dye intermediates for our consumers.
